This is super fun! Impressed that you made four distinct tracks with very different feels to them, and I think each one fits your narrative explanation pretty well!
I really like your melodies, thumpy percussion, and sizzly risers/transitional sounds! The weird formanty/vocal bass sound in RUNR. is extremely weird and a little upsetting in an intriguing and satisfying way, I love it.
The main mixing thing that stands out to me is that the different instruments all feel like they have different reverbs – consolidating them into a reverb send might help make everything sound a little more cohesive and grounded.
I think the lead synth in .startup might also be a little bit too aggressive, a tiny bit of EQ or lowering the volume would help a lot!
